The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900 and - 900ER airplanes. This AD was prompted by reports of cracks in the forward galley door cutout forward upper corner bear strap. It has been determined that the cracks were caused by high operating stresses in the fuselage skin door cutout corner area due to stress concentration at the door cutout. This AD requires an inspection of the fuselage skin and the bear strap at the forward galley door cutout forward upper corner for existing repairs, and applicable related investigative and corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes.

In a Report and Order, the Federal Communications Commission (Commission) finds that allowing FM booster stations to originate content on a limited basis would serve the public interest. The Report and Order adopts rules to allow for the voluntary implementation of program originating FM booster stations, subject to future adoption of processing, licensing, and service rules proposed concurrently in a further notice of proposed rulemaking, published elsewhere in this issue of the Federal Register. The rule changes in this document are needed to expand the potential uses of FM booster stations, which currently may not originate programming. The intended effect is to allow radio broadcasters to provide more relevant localized programming and information to different zones within their service areas.

The FAA is superseding Airworthiness Directive (AD) 2021-25-03 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. AD 2021-25-03 required operators to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected engine model. Since the FAA issued AD 2021-25-03, the manufacturer again revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life- limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The Securities and Exchange Commission ("Commission" or "SEC") is adopting amendments to a rule under the Securities Exchange Act of 1934 ("Exchange Act") that requires disclosures for order executions in national market system ("NMS") stocks. First, the amendments expand the scope of reporting entities subject to the preexisting rule that requires market centers to make available to the public monthly execution quality reports to encompass broker-dealers with a larger number of customers. Next, the amendments modify the definition of "covered order" to include certain orders submitted outside of regular trading hours and certain orders submitted with stop prices. In addition, the amendments modify the information required to be reported under the rule, including changing how orders are categorized by order size as well as how they are categorized by order type. The amendments, as part of the changes to the order size categories, modify the rule to capture execution quality information for fractional share orders, odd-lot orders, and larger-sized orders. Additionally, the amendments modify reporting requirements for non- marketable limit orders ("NMLOs") in order to capture more relevant execution quality information for these orders by requiring statistics to be reported from the time such orders become executable. The amendments modify time-to-execution categories and require average time to execution to be measured in increments of a millisecond or finer and calculated on a share-weighted basis for all orders. The amendments require that the time of order receipt and time of order execution be measured in increments of a millisecond or finer, and that realized spread be calculated at multiple time intervals. Finally, the amendments enhance the accessibility of the reported execution quality statistics by requiring all reporting entities to make a summary report available.
